Identification of Hemodynamically Optimal Coronary Stent Designs Based on Vessel Caliber [PDF]

open access: yes, 2012
Coronary stent design influences local patterns of wall shear stress (WSS) that are associated with neointimal growth, restenosis, and the endothelialization of stent struts.

Twin Circumflex Arteries: A Rare Coronary Artery Anomaly

open access: yesJournal of Tehran University Heart Center, 2018
A circumflex artery originating from an ostium apart from the left main artery is one of the most common coronary artery anomalies. However, a dual origin of the circumflex artery is an extremely rare anomaly.

Direct Quantification for Coronary Artery Stenosis Using Multiview Learning [PDF]

open access: yesarXiv, 2019
The quantification of the coronary artery stenosis is of significant clinical importance in coronary artery disease diagnosis and intervention treatment. It aims to quantify the morphological indices of the coronary artery lesions such as minimum lumen diameter, reference vessel diameter, lesion length, and these indices are the reference of the ...

Coronary Artery Centerline Extraction in Cardiac CT Angiography Using a CNN-Based Orientation Classifier

open access: yes, 2018
Coronary artery centerline extraction in cardiac CT angiography (CCTA) images is a prerequisite for evaluation of stenoses and atherosclerotic plaque. We propose an algorithm that extracts coronary artery centerlines in CCTA using a convolutional neural ...

AGFA-Net: Attention-Guided and Feature-Aggregated Network for Coronary Artery Segmentation using Computed Tomography Angiography [PDF]

open access: yesarXiv
Coronary artery disease (CAD) remains a prevalent cardiovascular condition, posing significant health risks worldwide. This pathology, characterized by plaque accumulation in coronary artery walls, leads to myocardial ischemia and various symptoms, including chest pain and shortness of breath.

DeepCA: Deep Learning-based 3D Coronary Artery Tree Reconstruction from Two 2D Non-simultaneous X-ray Angiography Projections [PDF]

open access: yesarXiv
Cardiovascular diseases (CVDs) are the most common cause of death worldwide. Invasive x-ray coronary angiography (ICA) is one of the most important imaging modalities for the diagnosis of CVDs. ICA typically acquires only two 2D projections, which makes the 3D geometry of coronary vessels difficult to interpret, thus requiring 3D coronary artery tree ...

Coronary artery spasm : role in acute myocardial ischaemia [PDF]

open access: yes, 1992
Coronary artery spasm is an accepted cause of transient myocardial ischaemia in patients with variant angina. The electrocardiographic abnormality, ST segment elevation, which is a hallmark of this syndrome, resembles that seen experimentally when the ...
